What lens do I need?

The question is not "what lens will cover the same range" but "what lens will cover my photographic needs".

I've been in the same place few years ago, coming from a bridge camera sony H2, big zoom range. After few years of DSLR photography I know perfectly what my needs are and what's they're not.

To sum up: what do you shoot the most? Macro? Portraits? Wild life? Architecture and landscapes? Answer those questions and we will guide you. I think that an all-around lens is not the best way to learn photography (others might disagree).

For instance: I currently own 14-54mm, 50ZD (semi-macro and portrait) and 40-150mm. Most of my pictures com from the 50mm and 14-54mm. Maybe 1 or 2% of the 40-150mm. I'm not a tele-lens shooter. But I do miss a wide angle lens. That why I know that when I'll jump to micro4/3 I'll need the 14-42mm, the 45mm and the 9-12mm lens and that's it.
